The differences in absorbability have led to the concept of dietary folate equivalents
(DFE), where 1 DFE = 1 [micro]g food folate = 0.6 [micro]g folic acid from fortified food or supplement (4).
Then, in 1998, dietary folate equivalents
were established--because of differences in bioavailability, or absorption--of at least 400 mcg per day for adults.
